    File plays fine here, it is vbr which might account for the varying results with players interrogating it...
    You think that's air you're breathing now?

    You can calculate the average bitrate manually. A 3 MB file that has a duration of 4 minutes would be:
    Code:
    (3 MB * 8192) / 240 seconds = 102.4 kilobits/second

    Re: Avconv Creates Files That Crash MP3 Player

    I can confirm this problem -- mp3s created from flvs with ubuntu's version of ffmpeg were unplayable on a SanDisk Clip+. I used ffmpeg -i $i -ab 192k -ar 44100 $i.mp3, and also avconv -i $i -ab 192k -ar 44100 $i.mp3, and playing mp3s so created froze the player. I replaced /usr/bin/ffmpeg with the ffmpeg static binary downloaded from the link provided in post #7 in this thread, converted same flv files to mp3s, and they now play without freezing. I'm using Mint 13 Maya. I routinely use ffmpeg, and this problem just appeared within the last week or three, so perhaps there was a change to ubuntu's version of ffmpeg that broke something. I had also arrived at the solution of converting flv to mp3 with Audacity, which produced mp3s that worked.
